I did a water change on my tank about 4-5 hours ago. I did it as i normally do, except I was using a new pair of gloves to protect my hands and I had forgotten to rinse them before using them. I had them on my hands while I tended to a few things in the tank.
about 10 minutes after the water change my clown began acting strangely. He became very listless, and even laid down on his side a few times. Now he is up and swimming but he his not his normal active all over the tank self, he is swimming in the same spot, still kind of listless. He will eat, although not as excited as he noramlly is for food.
My frogspawns and torch corals have shrunk down (looking like they would if the lights were off) and they should be out all they way by now.
my green encrusted "pagoda cup" polyps have not come back out.
My mushrooms, green stars, bubble coral, xenia, and othe misc zoos appear fine.

I am thinking since I did not rinse the new gloves before using them in the tank that maybe some sort of factory chemical may have been leached into the tank. Could I be right? Or am I overreacting to something that is not a big deal?

They were the standard yellow dishwashing gloves that you can get at any grocery store.
I changed out 1 gallon of water. I used the same distilled water and salt mix as I always do. Clown is still acting dazed.
I did the water change as I normally do. I scrub any nuissance algae, then I start the siphon, suck up some junk in the aragonite. Then I fill it up with the new water and turn the pump back on.

I mixed the water about an hour before the change. I always make sure that the temps and salinity match in the tank and in the new water before adding. I added some extra carbon to (hopefully) absorb anything that may be causing the problems.
Yeah, I would prefer to leave the pump on during the change too, but it sucks in way too much air to allow it.
I think am going to do another water change in the morning just to be safe. How much do you recommend I change?
